Yep!
I can mistaken, maybe order should be different.
I've just messed up with those commands and suddenly it worked.

@slowcyclist Thank You very much!

I've just copied and pasted some of lines from your topic and USB-tethering WORKS NOW!!!
(I don't know why )
Here are that commands:
$ sudo android-gadget-service enable rndis
$ sudo bash /android/system/halium/usr/share/usbinit/setupusb reset
$ sudo bash /android/system/halium/usr/share/usbinit/setupusb rndis
$ sudo ifconfig rndis0 up
$ sudo tethering enable

Please, test it sombody else with Oneplus3.

Thank You all!
I was confused by the fact that someone said that he had this feature on Oneplus 3.
So...
I hope we will have this in nearest future.
Have a nice day!
